If he took doping then it's his own fault, but I wonder if any cyclist out there is really "clean"... Performances they are showing nowadays look pretty superhuman to me.
It's a shame, because they are ruining their own health with it.

The sport now gets what it deserved for being so tolerant in the past. Drugs represent a health hazard issue, if they were safe then you could allow free access to everybody, that would include amateurs doing recreational workouts, but obviously drugs are not safe.
